CBD oil is a natural remedy derived from the cannabis plant that has gained popularity for its potential health benefits. CBD, or cannabidiol, is one of over 80 chemicals, known as cannabinoids, found in the Cannabis sativa plant. Unlike THC, the main psychoactive cannabinoid found in cannabis, CBD does not cause a "high" by itself. CBD oil is made by extracting CBD from the cannabis plant and diluting it with a carrier oil like coconut oil or hemp seed oil.

CBD oil has been studied for its potential use in treating a variety of conditions, including anxiety, pain, movement disorders, and cognition. However, there is insufficient high-quality evidence that cannabidiol is effective for these conditions. CBD is a herbal dietary supplement promoted with unproven claims of particular therapeutic effects. Nevertheless, CBD may be effective for reducing certain types of pain associated with conditions such as fibromyalgia, and it has shown promise as a treatment for some mental health disorders.

CBD oil derived from hemp (with 0.3% THC or lower) is legal to sell as a cosmetics ingredient or for other purposes not regulated by the FDA, but cannot be sold under federal law as an ingredient in food, dietary supplement, or animal feed. CBD products made from hemp are no longer considered Schedule I drugs under the federal Controlled Substances Act, but they still remain in a legal gray zone. CBD products are largely unregulated in the U.S. market, and independent testing has shown mislabeling and lack of quality control. Therefore, it is important to be a cautious shopper and look for products manufactured in the U.S. with ingredients that have been tested by a third-party lab.
